Title: Improvements in or relating to power transmissions
IPC: F16H39/06
Filed: 1935-02-04
Abstract: 448,953. Rotary engines. LEVETUS, F. B., and KEELING, G. V., M.W. Service Station, Pickford, and BOOTH, E., 95, Butt Lane, both in Allesley, near Coventry. Feb. 4, 1935, No. 3628. [Class 110 (ii)] [See also Group XXIX] In a power transmission system a variablecapacity pump 2 of the rotary-abutment type supplies liquid to rotary-engines 18, 19, of the same type, upon a driven shaft 26. The pistons 3, 21 upon the pump and engine rotors, and co-operating recesses 9, 24 are shaped as described in Specification 448,951. A sleeve 13, in a recess 14, may be thrust axially to gradually fill the pumping space, slots in the sleeve accommodating the pistons 3. The sleeve pushes the abutment 8 axially so that when sleeve and abutment reach their extreme left-hand position no liquid is pumped from an inlet 16 to a delivery 17 which leads to the engine chambers. Figs. 3, 4 show means for controlling the flow from the pump to the engine. The pipes 17, 28, from and to the pump, are divided into branches 17a, 17b, and 28a, 28b, and according to the angular position of a plate valve 30, containing slots 17c, 17d, 28c, 28d, liquid flows from the pump to the engine to drive it in a clockwise or anticlockwise direction. As shown in Fig. 4, the pipes 17, 28, are connected through the valve plate 30 with apertures 17e, 17f, 28e, 28f, and the engine is short circuited. The pipe 32 leads to the engine, and 33 back to the pump.

IPC: B01J39/00
Filed: 1955-02-14
Abstract: To reduce the radio-activity of radio-active liquids there are used ion-exchangers in which heavy-metal ions having an atomic weight in excess of 100 are associated with or substituted for the usual ions. Examples of such heavy-metal ions are those of barium, silver, lead, cadmium, bismuth and mercury.  In the first alternative the association of ions (the "usual" ions being, for example, those of alkali metals) may be in a single exchanger or in two exchangers in series, the first containing the heavy-metal ions and the second the "usual" ions.  The liquid may be passed through a filtering candle or a diaphragm comprising the ion-exchangers either bodily in permanent form or on its surface in the form of an easily-renewed bed.
